/o adieu/1.0m t may concern f Be it known that l, Tlvl/vinimiivr H., Nonn-v riAUs, a citizen of the United States, residing at Chicago, in the county of Cool; and State of lllinois, have invented certain new and useful Improvements in Tables for Fasting Storage-Battery Plates, of which the followin is a specification.l

y invention relates to a table designed to facilitate the -lilling4 or pasting oitlead grids, or grids composed 0f an alloy of lead and other inetals such as are used in the construction ci electric storage batteries, with the paste which forms their active material. This paste, in the form of a moist plastlc material composed mainly of red lead,

litharge, and usually some other ingredients,

according to the particular formula employed, and capable of being worked by hand Ainto a coherent mass in the grid'openings, is applied' to the grids, lirst to one sideand" then-to the other, the surplus paste being struck oli" by a suitable straight-edged blade or pasting knife land theV operation being.

carried cut in such manner a's to completely till the grid openings and leave a smooth vsurface on each side llush with metal of the grid. The usual practice in pasting plates is to lay down a row of grids on a smooth table; then rub or force the material into the grid openings and strike'olf the surplus material from the upper surface; then apply to each pasted face a sheet of paper the saine size as the plate, then reverse the plates one by one; then'repeat the filling operation on the other side; and finally strip ofi the paper and stack the plates one by one on a drying rack. The object-o;33 my present invention is toprovide an apparatus by means of which this worlr may be carried on with greater described, withv consequent decrease in the cost ori the labor To this end l have devised and invented tlfieunovel table hereinartter described and which is illustrated in the accompanying ,'drawings, the .essential elements of my invention being 'recited in the appended claims, it being understood, however, that various modifications in the forni and arrangements of parts and the substitution oi? equivalent elements for thosedescribed are possible, without departing frein4 the spirit of niv invention-or the scope .of the cit-tires. l v

Of the drawings, Figure l is a perspective ofthe table showing one rotatable plate support in position to receive a row of plates; Figs. 2 and 3 arerespectively aplan view and a side viewv of the saine; Fig.. l is 'a cross-section on the line 4f-4 of Fig. 3; Fig. 5 is a fragmentary section in the same plane, but without the plate support in place; F ig. 6 is a plan View ofthe table with a portion Fig. 7 is a broken top'v view of the plate support; F ig. 8 is a side view of the two plate supports arranged face-to face in position to be rotated; F ig. 9 the same; and Fig. 10 a perspective of almodiied form of end bearing for thev plate support. j

The saine reference characters indicate the same parts in all of the figures of the drawin s.

he dill'erent parts of theframe work of my novel table maybe formed of Wood or any suitable structural material united and secured together by suitable means to producea substantial, rigid structure. At one 'eiidcf'the frame is arranged a supply table l, provided at the rear and end and part of the :iront side with marginal vertical anges and adapted to receive a supply of the paste used for lilling the grids. At the other end of the frame a plate table 2 is provided to receive drying racks upon which the filled plates niay be stacked, to be removed from -time to time as they accumulate. intermemoved after the two supports havebeenjro#v tilted, and the support a the position and take the cupied by the support 4.

These end bearings, in the present instance comprise curved end blocks 6a, ,the end portlons of the support. member 4 and yplates 6P- securedtor the top of A.the support, such plates being efe . 100' lace formerly 0c.,

sired number of grids,-twelve in the table shownin the drawings. This specific construction of the end bearings, however, while convenient and desirable, is not essential to my invention and the parts of such bearings may be made integral or dierently formed and secured together in the relationship described. In order to give strength and rigidity to the supports,they are each provided with a bottom longitudinal rib 8 extending between the end blocks 6". and brackets 9 are interposed in the angles between the rib 8 and the support. One edgeof each of the supports 4 and 4a is provided with a series of stops, marked 10 and 1()EL respectively, the two series being staggered and so spaced that when the supports are arranged face to face each grid may abut against both a stop 10 and a stop 10a. These stops are preferably somewhat less in height than the thickness of the grids in order to prevent interference with the knife or scraper in striking ofi'l surplusmaterial. If not more than half the thickness -of the grid they may be opposite each other, and not staggered, as shown and above described. Y

p Constructed as above described, the manner in which the lead grids are pasted to form battery plates is as follows: One of the two supports, as for instance the support 4, being placed in the seats 7, a row of grids is arranged on its-recessed top surface,as bestshown in F ig. 2. The grids are now-pasted with material taken from the supply table 1, and the surplus material struck off with the pasting knife, falling into the waste hopper 3, and a Asingle sheet of paper of the proper -size to cover all the grids is placed on top of therow. The support 4a is now placed face down on top of the support 4, in the position shown in dotted lines in Figs. 3 and 4, and

the two supports now rotated togetherk toward the Workman, that is in such manner that `the stops 10 and 1()a will travel downwardly during the first quarter revolutionl and then upwardly, in which position they will `prevent the grids from falling out'of their seats. When the grids are brought into vhorizontal position a ain with their uncoat# ed sides uppermost, t e support 4 is removed and the paste is applied to the uncoated side of the ygrids andthe surplus material struck ofi' as before, andthe filled plates then lifted one by one, a section of the paper shearing od at the edge of each plate as it is lifted and being lifted with it, and these sections of paper being then removed the plates are stacked in a suitable drying rack on the plate table 2. The succeeding operation is conducted in the same manner, except that the supports and plates are rotated in the opposite direction, in order that the stops may -travel first downwardly and then upwardly and support the plates during the reversing operation.

If desired, both sides of the supports may be provided with stops in which case the supports may be rotated in either direction. In such case it will 'be necessary that the stop shall be so located as to avoid interference with the connecting tongues which ordinirily project from one corner of the gri s. y i

The bearing surface of the supports constructed as above described and as illustrated in the drawings has been found in practice to afford sufficient frictional resistance in turning to make them stable, but if desired, locking means may be provided to restrain them from rotation while the plates are being pasted, in which case the bearing blocks may have a relatively small bearing portion and be made as nearly frictionless as practicable. In F ig. 10 I have shownsuch a modification of my invention, the semicylindrical journal 12 of the bearing being formed as an integral portion of the end plate 13 of the support, and a sliding bolt 14 provided for the purpose of locking the support in working position.
